Summary

Libertia peregrinans, commonly known as New Zealand Iris, is an evergreen perennial herb native to open woodlands and grasslands in New Zealand. It typically grows to a height of 1-3 feet (0.3-0.9 meters) and a width of up to 1 foot (0.3 meters). This plant features stiff, upright, sword-shaped leaves that are a striking orange-brown to bronze color, providing year-round interest. The white, iris-like flowers bloom in spring and early summer, and although they are not particularly showy, they do add a subtle charm to the garden. After flowering, attractive seed pods may form.

New Zealand Iris is valued for its unique foliage color, which can add contrast to garden plantings. It is used in cultivation for mass planting, as an accent in borders, or in contemporary gardens for its architectural form. It requires well-drained soil, tolerates a range of soil types, and is relatively drought-tolerant once established. While it prefers full sun or part shade, it can tolerate a variety of light conditions. This plant is generally low-maintenance but can be affected by slugs and snails. It is also known for its clumping habit, which can be divided in spring to propagate new plants.CC BY-SA 4.0
